CARf BUMPER.

- Appneanm medmugustis, 1924:v senat Noi732g4s4a Chicago, in thefcounty of Cookv and State of Illinois, have yi nventeda newand 'useful Improvement in Gar vBumpers, ofk which the` following is a specification;

This invention relates to? improvements in car dumpers, and more: especiallyuto that typeof car 'dump'er comprisingza cylindrical rotatable cage adaptedftof contain a :car'f toy be dumped; In such dumpers,.rotation. ofthe` cage? serves lto invertthe` car and dump the contents.. My- 'inventionv relates more particularly to the methodf and. mechanism i of rotating. the cage, stopping the same', and the like.

' My improved dumper is easy and cheapto constructand ea'sy to. operate and' lmaintain. Its construction isv strong and rugged. Other! features and i advantages' of my invention will appear' morefully as I proceed with =1ny'specification;

In that formof devicelembodying'the'features of my invention shown inlthe accom'- panying drawings,` Figure 1fisaview in .side elevation of a complete cari dumper, E1g'..2 isadtop planI view ofi the". same, Fig. 3 is a View taken as indicated by the line 3-3 of Fig. 1, Fig. 4 is a view on an enlarged scale showing the driving wheel and brake shoe, Fig. 5 is a view taken as indicated by the line 5 5 of Fig. 3, and Fig. 6 is a top plan view showing the driving wheels and brake shoes.

As shown in the drawings, 10, 10 indicate the ring rails which are suitably joined by struts, braces, and the like 11, 11, 1n order to form a complete cylindrical cage adapted to contain a car 12 resting upon the rails 13, 13 in the cage. The cylindrical cage is rotatably supported on the four wheels 14, 14; a ring rail 10 resting on a pair of such wheels at each end ofthe cylindrical cage. Any suitable means such as angle irons 15, 15 are mounted within the cylindrical cage to occupy a position above the wheels 16, 16 of the car 12 in order to hold the same on the rails 13, 13, during the dumping operation.

I will now describe the construction and operation of the mechanism for rotating the cylindrical cage and stopping or braking the same. 17 indicates a rotatable shaft extending substantially the entire length of the cylindrical cage. On each end of the shaft 17 ismounted af driving.- wheel 18 adapted toengage vwith oneof the i'ingfrails 10. The" shaft 1-7nvith'1the'f driving `wheels .18 is adaptedtofrotate continuously. lVhen it isV desired to rotatethc cage, the driving wheels 18, 1:8'alre' moved into frictional engagementwith thezring. rails-10, 10. When it is desired to release. the: power from the cagethe driving. wheels are movedl out of contact with the ring rails; I will now describey thel means for` so' mving. the driving Wheels 18; `18finft`oorI out of Contact withy the ring rails.. The ends. of the shaft 17@ are mounted iny eccentricl lbearings- 19, 19, which in -turn are rotatably: supportedin blocks-20, 20,.resting-'onthe1beams'21, 21. Each of the eccentric bearings 19 is: circular' on `its outer surfacefwheref itrests in the block 20 but the circular hole infthebearing carrying the shaft-17 is-eccentrically arranged. By this construction, rotationfof the bearings19, 19 in the blocks 20, 20,obviously will causefthe driving. wheels'18, `1'8fto approach or recede from the ring.rails-10,1110.I The'two eccentric bearings 19VA are connected byy the hollow.- tubev 22, so. thatl these bearings will alwayszmove together.. Rotation ofthe eccentric bearings1v19;.19f,-is eiiected'j in the following manner. One of these bearings carries a downwardly projecting arm 23 to which is connected a rod 24, which in turn is connected to the operating lever 25.

Movement of the operating lever serves to twist the bearings 19, 19, in the blocks 20, 20, to move the driving wheels 18, 18, into or out of engagement with the ring rails 10, 10.

Mounted on the beams 21, 21, adjacent the blocks 20, 20, are also tWo bearings 26, 26, carrying the rod 27. On the ends of the rod 27 are two brake shoes 28, 28 adapted to be moved into or out of contact with the ring rails 10, 10, by rotation of the rod 27. The rod 27 is provided with a downwardly eX- tending arm 29, to the lower end of which is attached a bar 30 having one end also attached to the rod 2a at 24a. The parts are so arranged that movement of the operating lever 25 in one direction serves to rotate the bearings 19, 19 to move the driving wheels 18, 18, into frictional engagment with the ring rails 10, 10. Such movement of the operating lever serves to rotate the rod 27 to swing the brake shoes 28, 28, out of engagement with the ring rails 10, 10. Movement of the operating lever 25 in the opposite direction serves to draw the driving wheels 18, 18, away from the ring rails 10, 10, and thence move the brake shoes 28, 28, into contact with such ring rails to stop the momentum of the cage.

rllhe shaft 17 carrying the driving wheels 18, 18, may be rotated in any suitable man'- ner. I have here shown an electric motor 31 adapted for such purpose. Power is transmitted from the motor 31 through the pinions 32h83, 34, and 35, as shown, to the shaft From th shaft 36, power is transmitted to the shaft 17 by the intermediary shaft 37. The ends of the intermediary shaft` 37 are provided with two jaw clutches 3S, 3S in order to give the requisite flexibility, to permit the turning of the eccentric bearings 19, 1S), in the blocks 20, 20, during the continuous rotation of the shaft 17.

wWhile I havel shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as possible in view of the prior art.

What I claim as new, and desire to secure by Letters Patent, is:

l. In combination with a cylindrical rotatable cage having ring' rails mounted on supporting rollers; a driving Wheel arranged adjacent one of the ring rails, said driving wheel being carried by a shaft mounted in an eccentric bearing; a brake shoe adjacent one of the ring rails and mounted on a shaft rotatably supported parallel to the shaft carrying the driving wheel; and means for simultaneously rotating the eccentric bearing to bring the driving wheel into contact with the ring rail and rocking the shaft carrying the brake shoe to move said brake shoe out of contact with the ring rail; and vice versa.

2. In combination with a cylindrical rotatable cage having ring rails mounted on supporting rollers; a pair of driving wheels arranged adjacent the ring rails and mounted on a shaft carried by eccentric bearings rotatably supported in blocks; means for rotating said bearings in .said blocks; a shaft arlangedparallel to the shaft carrying the driving wheels; a pair of brake shoes mounted on said last mentioned shaft arranged adjacent the ring rails; and means for rotating said shaft carrying said brake shoes.

3. In combination with a cylindrical rotatable cago having ring rails mounted on supporting rollers; a pair of driving wheels arranged adjacent the ring rails and mounted on a shaft carried by eccentric bearings rotatably supported in blocks; a shaft arranged parallel to the shaft carrying the driving wheels; a pair of brake shoes mounted on said last mentioned shaft arranged adjacent the ring rails; and means for simu1taneously rotating the shaft carrying the brake shoes and the eccentric bearings in their supporting blocks,

lVitness my hand and seal this 14: day of August, A. D. 1924.
